I switched out the motherboard on a socket 478 computer with a 3.2 ghz chip and hooked everything back up and turned it on and the standby light comes on and both fans, but no picture or bios setup. Any ideas, I tried to jump the cmos, but that did nothing. The board is different than the original, but it supports the p4 chip up to 3.2 and the hard is good, but the darn thing will not start up to get the computer and peripherals talking again.

Re: Won't go into Bios or display anything
Hi kwilson709, you sound like you know what you’re doing. Did you hear any beeps when you first started up the system? Your must use the Intel (Northwood) CPU on the AOpen AX4SG-UN. Make sure the 4-pin 12V. ATX Power Connector is seated & locked, same with the 20pin ATX main power connector. When you clear the cmos jumper, pg 24 in your manual. Remove the battery & check its voltage for 3 volts, if it reads anything less replace the battery. If your graphics card is an add on & not integrated on to the motherboard, remove & blow out the slot with canned air & clean the contacts with a couple drops of alcohol on a cotton swab or to & reseat. Do the same for your memory. If the graphics card has dual VGA out puts check both for possible display. Make sure the monitor works. (One never knows). Try one DIMM if you are running two DIMM's or more. If all of the above fail, it’s suggested that you remove the motherboard from the case & lay it on a table with a piece of cardboard under the motherboard. Hook up your power supply, graphics card (If you’re using one), memory (One DIMM & hard drive, mouse & keyboard. Once everything is connected short the two pins for power on with the tip of a pen to start up the system. Check for display. Still no display? (Only if you have one), try a lower MHz compatible CPU. Other than what’s mentioned above I'd say it’s the motherboard. (Testing the motherboard out side of the case is used to eliminate a possible case issue).

If your processor 2.4 Ghz HT you need socket 478 motherboard,System bus 800.without HT you need 533 FSB Motherboard.You can buy easily.Where you live? I do not know.China are available made 478 PIN mother board.
if the sci36-r13 is the stock mobo that came with that pc it isnt worth upgrading pentium 4's use the LGA-775 socket this is compatible with all pentiums and core 2's (not includeing core i7), so you could put in a core 2 quad if you wanted to but it would not make much difference to performance because your motherboard would not be able to handle some of the fetures your ram would also reduce preformance
if you wanted to upgrade that computer you would have to replace everything but maybe the case
Supports processors at 400 / 533MHz front side bus
Or higher, it says. But doesn't say how higher. It's a fair assessment that if it is a Pentium 4 socket 478 chip, it should work. Then it's a case of choosing one that suits your budget.
Have a look on the Asus site for the latest BIOS updates too - they might have a clue as to what chip you can go to - http://support.asus.com/download/download_item.aspx?model=P4S533-MX&product=1&type=All&SLanguage=en
Er, no - it doesn't tell you. But if you go thru the page you will find BIOS version 1005 that "
P4S533-MX BIOS 1005 Support new Intel P4 CPU" and the latest bios is 1007.002 There's a motherboard user manual further down on the page. Make sure you choose the English one. Seems the issue is FSB speed, 533 or 400. No big problem for most, but I did see a Pentium4 3.0Ghz chip at 800 FSB so just check the speed of the processor matches the specs the motherboard handles. Like you say, looks like the 3.2 might be too fast because of the FSB requirement. Remember, a P4 is going to be quicker than a celeron anyhow so just go with the fastest 533 FSB chip you can find. A short-cut to the english manual, here - http://dlcdnet.asus.com/pub/ASUS/mb/sock478/p4s533-mx/e1187_p4s533-mx.pdf
are you using socket 478 motherboard or socket lg775 motherboard? if lg775 mobo you using try to remove the cpu heat sink and put it back again make you put correctly lock it perfectly and try to switch it on
you may check
1) your Intel pentium 4 3.2 GHZ cpu socket 478 processor #sl7nb what's FSB?( see on the chip surface, if 533 FSB can use but 800FSB could not match your motherboard if which is not support 800 FSB. that's why no display.
2) check RAM stick speed, try to increase a level, for example 266 to 333.
is this helpful please feedback thanks
